我有一个带有几个字段的JSF页面。我跟着BalusC的这个tutorial，一切都很好。然后我添加了RichFaces支持，它工作正常。我可以看到弹出窗口等工作。如何从richfaces弹出窗口刷新父级jsf页面
现在我所要做的是，一旦一个人已被注册，我要显示在弹出的名字（这也是很好我可以看到，在弹出）。然后，我想能够在弹出窗口中更改该名称，并将其反映在父项中，但我不知道如何做到这一点。请看一看。

感谢回答，我明白你说的话（我认为:)），但未能得到正确的代码。我给了名为“form”的原始表单ID，并以其他形式将面板外部移动，但弹出窗口仍然不关闭，也没有更新调试点显示它正在触摸该方法，但屏幕流程不正确，请参阅我的更新问题结束。非常感谢您的回复。谢谢 –
表格需要*在面板中，而不是围绕它。另外，按钮应该关闭对话框（例如通过脚本）。 –
不能感谢你是伟大的。你和Blusc的工作原因:) –
